HAIR THICKENING METHOD Filed Dec. 17, 1963 M 75 1 F/6.2/ m) A r; A L (ii INVENTOR. JESS poet/M ArrareA EY United States Patent This invention relates to apparatus and a process for permanently attaching additional strands of hair to live hair to thicken the amount of hair on a persons head.

It is well known to secure artificial hair pieces to the head by means of adhesives or by physically inter-weaving the said hair piece with the existing hair on a persons head. However, such methods and apparatus either produce an artificial end result or make it impossible for the wearer to comb or wash his hair in the customary manner. In addition, the thickening process achieved by prior art devices is extremely localized and does not present an overall natural appearance.

Accordingly, it is an object of the present invention to provide a means for attaching additional strands of hair to the live hair of a person in a permanent and lifelike appearing manner.

Another object of the present invention is to provide a method for thickening the amount of hair on a persons head without interfering with the normal care of said hair.

Another object of the present invention is to provide a method for thickening the amount of hair on a persons head whereby individual .areas may be selected for such treatment or an overall distribution of hair may be applied.

A feature of the present invention is the use of strands or groups of strands of hair either natural or artificial which are adhesively secured directly to the existing hair of a person.

Another feature of the present invention is the use of an adhesive which 'will withstand washing and combing without becoming dislodged from the persons natural hair.

Another feature of the present invention is the use of artificial hair having a plurality of branches whereby a hair thickening effect may be achieved.

Another feature of the present invention is the use of a hair-like structure which may be secured to existing hairs in such manner as to provide a smooth readily combable end structure.

The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawing, forming a part hereof are illustrated several embodiments of the invention, in which drawing similar reference characters designate corresponding parts, and in which:

FIGURE 1 is a view in side elevation of a persons head showing the manner in which hair is secured to existing hairs.

FIGURE 2 is a somewhat diagrammatic view on an enlarged scale showing the manner in which additional strands of natural or artificial hairs are secured to existing hairs.

FIGURE 3 is a fragmentary view of a portion of a persons head showing the application of artificial or natural hairs to the live hair on a scalp.

FIGURE 4 is a view similar to FIGURE 3 showing a further embodiment of the present invention.

FIGURE 5 is a somewhat fragmentary view greatly enlarged showing the application of a branched artificial hair to an existing live hair on a persons scalp.

FIGURE 6 is a somewhat diagrammatic view showing the manner in which the live hair on a persons scalp ice may be held during 'the attachment thereto of artificial or supplementary hair strands.

Referring to the drawing, and particularly to FIG- URES 1 and 2, 10 indicates the scalp of a'persons head on which it is assumed there is growing a certain amount of live hair 11. In accordance with the practice of the present invention it is desired to increase the number of hairs on the scalp 10, by the attachment of artificial or natural hair 12, to the existing live hairs 11.

As shown in FIGURE 2 the attached hair 12 may consist of a single strand of hair or several strands 13. In either event, the hair 12, 13, is secured to the base of the live hair 11 by means of a suitable adhesive. A satisfactory adhesive for this purpose must be capable of withstanding repeated washings and must be strong enough to hold the artificial hair to the live hair during combing operations. Such an adhesive may be selected from any of the well known two-part cold curing systems of urethane based adhesives. These adhesives will not injure the existing hairs and will remain effective throughout continued periods of washing and combing.

By securing the artificial hairs 12, 13, to the base of the existing hairs 11, it is possible to run a comb through the combined hairs so as to eliminate tangles, knotting, and to provide for a part in the usual manner of hair care. In FIGURE 3 there is shown the application of a group of hairs 13 to a group of existing or live hairs 14. The existing hairs 14 are held in the manner illustrated in FIGURE 6 as by means of a comb 16, so that the base of the hairs 14 is exposed. The hairs to be added to the live hairs 14 are then dipped into an adhesive 15 while held by a suitable tool (not shown). The hairs 13 with the adhesives 15 thereon are then brought to bear against the bases of the natural or live hair 14, as shown in FIGURE 6. As soon as a bond has been effected between the live hair and the supplementary hair 13, the same operation may be repeated at another portion of the scalp.

In order to bring about a rapid thickening of hair it is possible to employ an artificial hair shown in FIG- URE 5 and indicated at '17. This hair is branched as shown at 18 so that a plurality of strands extend from a common stem 19. The common stem 19 is secured to the live hair 11 of a person by means of the adhesive 15 in the manner hereinabove set forth. It is sometimes desirable that the stem 19 be tapered at the bottom thereof as indicated at 20* so that a smooth juncture is achieved at this point between the live and artificial hairs.

From the foregoing it will be seen that there has 'been provided a method of attaching artificial or supplemental hairs to the live hair of a wearer in a permanent natural looking way. The applied hair is permanently attached to the existing hair and may be washed or combed in the same manner as .a persons natural hair is. treated. The amount of hair thickening which can be achieved is entirely dependent on the number of hairs to be added and the distribution of the hairs will depend upon the judgement of the person applying the said hairs.

In the process of applying the'artificial hairs to the living hairs, the living hair is first washed very thoroughly to remove as much of the natural oil therefrom as is possible. This step is important for the purpose of improving the adhesion of the artificial hair to the living hair. Thereafter additional hairs are glued in place as described above.

Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent of the United States, is:

1. The method of permanently securing supplemental hairs to the existing hairs on top of the head, comprising the steps of applying adhesive to one end of a first group of parallel, coextensive hairs having opposed free ends, securing the group of hairs to a second group of adjacent, natural hairs on the top of a persons head by attaching the adhesive ends of the first group to the ends of hair in the second group that are in contact with the scalp in a manner so that both groups lie generally parallel with each other, and repeating the above steps in sequence, as desired, for thickening the amount of hair on a persons head.

2. The method of permanently securing supplemental hairs to the existing hairs on top of the head, comprising the steps of Washing the existing hairs on top of the head to remove the oil therefrom, applying adhesive to one end .of a first group of parallel, coextensive hairs having opposed free ends, securing the group of hairs to a second group of adjacent, natural hairs on the top of a persons head by attaching the adhesive ends of the References Cited by the Examiner UNITED STATES PATENTS 1,831,801 11/1931 Birk 13253 1,897,747 2/1933 Birk 132753 2,079,256 5/1937 Kaiser 132-53 7 3,003,155 10/1961 Mielzynski et a1. 132-53 X RICHARD A.
